Pardee President and Chief Nuclear Officer Exelon Nuclear 4300 Winfield Road Warrenville,IL 60555 SUB..IECT: REQUEST FOR WITHHOLDING INFORMATION FROM PUBLIC DISCLOSURE FOR BRAIDWOOD STATION, UNITS 1 AND 2, AND BYRON STATION, UNIT NOS. 1 AND 2 (TAC NOS. ME1613, ME1614, ME1615, AND ME1616)

Dear Mr. Pardee:

By letter dated June 24, 2009 (Agencywide Documents Access and Management System (ADAMS) Package No. ML091770543), Exelon Generation Company, LLC (the licensee),

requested that the information contained in "WCAP-17072-P, "H*: Alternate Repair Criteria for the Tubesheet Expansion Region in Steam Generators with Hydraulically Expanded Tubes (Model D5)," dated May 2009 (Proprietary), be withheld from public disclosure pursuant to Title 10 of the Code of Federal Regulations (10 CFR), Part 2, Section 2.390.

The affidavit stated that the submitted information should be considered withheld from public disclosure for the following reasons, among others:

(a) The information reveals the distinguishing aspects of a process (or component, structure, tool, method, etc.) where prevention of its use by any of Westinghouse's competitors without license from Westinghouse constitutes a competitive economic advantage over other companies.

(c) Its use by a competitor would reduce his expenditure of resources or improve his competitive position in the design, manufacture, shipment, installation, assurance of quality, or licensing a similar product.

(e) It reveals aspects of past, present, or future Westinghouse or customer funded development plans and programs of potential commercial value to Westinghouse.

Section 2.390(b)(1 )(iii) of 10 CFR Part 2 of the Commission's regulations requires that each supporting affidavit contain a full statement of the reason for claiming the information should be withheld from public disclosure. The section further requires the statement to "address with specificity" the considerations listed in 10 CFR 2.390(b)(4).

The affidavit has been reviewed in light of the aforementioned paragraphs of the regulations and the general public availability of some of this information. The NRC staff requests clarification regarding how each of the information items listed in the enclosure meets the considerations of 10 CFR 2.390(b)(4) so that we may make the required determination under 10 CFR 2.390(b).

Please provide the clarifications within 30 days of the date of this letter.

C. G. Pardee -2 If you have any questions regarding this matter, I can be reached at 301-415-1547.

Sincerely, D~. c.~
